Now we’re getting somewhere! This looks really great! I would recommend maybe some fuel tanks or small props for the main areas; containers are great too. This is where you start telling the story with your environment. Off the top of my head, the story I think of is that the people here were trying to evacuate (thus you can litter some boxes/containers and other elements of chaos around) and had to leave faster than they wanted to. Just an idea though, you can do what you think works.
Keep up the great work!
